WINDSCREEN WASHER HOSES, CHECKING AND RE-ROUTING

Windscreen washer hoses, checking and re-routing 

1. Checking position of hose and hose routing (see Fig 1 )

   Check the hose on the left and right side nozzle: it should not be kinked and should form a loop (A) of not less than 35 mm (~ 1 3/8 in.).

   NOTE: The hose must in no way be pinched or kinked, nor have any tendency to kink.

   On the right side, check if the hose is pinched by the hood insulation panel (B). If necessary, mark where material needs to be removed.

   If the hose is pinched by the hood insulation only: Remove material from the hood insulation panel as marked to ensure that the hose lies in place freely.

   If further obstructions, such as pinching or kinking, are found elsewhere, see the following method.

2. Rectify nozzle connections if necessary (see Fig 2 )

   Remove hood insulation panel completely.

   NOTE: Always replace existing hoses with new hose. Fit so that pinching cannot occur when hood insulation panel is refitted.

   Cut hose to the correct length:

   Left: +/- 560 mm (~ 22 1/16 in).

   Right: +/- 160 mm (~ 6 5/16 in).

3. Affected vehicles: 2000-2001, cars with headlamp wash/wipe (see Fig 3 )

   Replacing hose from T-valve on inner fender to T-valve on hood

   Remove:

   • hose bend (C) from its fastening on the hood (MY 2000)
   • hose (G) that runs from connection (D) along the inner fender to connection (E).

   Install new clip (C) (MY 2000 vehicles).

   Slide new hose (G) through the mounted clip (C) and through openings (A) in hood by the T-connector (E) and connect.

   Push hose (G) into clip (B) on inner fender and pull straight through to the front. (do not bend)

   Measure off a length of hose (G) sufficient to reach T-connector (D), and cut to length. Connect the hose to the T-connector.

   NOTE: Verify that the hose fits snug along the inner fender and does not kink or pinch when closing the hood.
